I'm not sure that it's possible to pronate through impact. You'd hit the ball with the sole of the club instead of the face.

That is typically what happens. Keep in mind that the normal tendency due to the arch of the swing is for the club head to rotate counter-clockwise through the impact zone. Therefore, a player who is pronating through the impact zone is very likely to still have some of that counter-clockwise motion, so it is possible to still hit the ball on the club face.

Ben Hogan explained it far better than I ever could. The interesting part is that now that I have cured the habit, I find it extremely difficult to mimick the behavior. Even so, it probably makes more sense to show rather than tell in this case.

The more I examine the wrist action the more I realize it to be the very essence of the swing. Maybe it's different for everyone, I don't know. I am not really seeking out universalities. All good swingers do roughly the same shit at impact, but everyone's sensation is unique. Like snowflakes, no two of them are wholly alike. Similar maybe, but different enough to cause a world of confusion and misunderstanding.

When I stand in an address position, and then waggle the club back and forth via the flexing of the wrists, what might appear as some half-brained, willy-nilly move is actually a defining of the optimal swing plane through impact. That's kind of a big deal.

Now finally understanding the significance of wrist cock. Jesus Christ FINALLY. Only took like, 13 years. God, what the hell is wrong with me?

Ok so previously I was wondering if wrist cock is the essence of the swing. I don't think that's quite it. Wrist cock doesn't really exist on its own so much, it's always blended with the rotation of the entire self. They work in sync. What I had considered the essence of the swing is really just the portion of the swing from 9 to 3:00 or whatever. The wrist hinge keeps the club on plane while the core rotates, or something. Not exactly a deep insight. But as I say accepting my own stupidity is an essential part of the moving forward process.
